- Replace placeholder with OpenCV.js WASM perspective correction:
pick highest-confidence rectangle, compute homography, fold
weighted scale corrections from secondary datums, single warpPerspective
- All units now mm throughout (no cm conversion)
- Simplified datum creation: two buttons (+ Rectangle / + Line) with
preset chips, auto-numbered labels (Line 1, Rectangle 2, etc.)
- Dimensions default to 0, user must input manually; Next button
disabled until all datums have valid dimensions with tooltip hint
- Fix image preview (keep object URL alive), fix canvas disappearing
on breakpoint switch (single instance + ResizeObserver re-fit)
- Mobile responsive: bottom sheet for datum panel, full-width canvas
- Spinner on result screen during processing
- Stricter ESLint config, updated Prettier to 4-space/no-semicolons
